Abstract

Antenna of the present invention comprises the half-wave doublet (2,3) that conllinear is arranged, at two terminal half-wave doublets (2 1, 3 n) one side place a quarter-wave symmetrical dipole (6,7).Oscillator is inductive and capacitive character phase shift 60 to 120 degree alternately.The terminals of antenna draw the abutting end from the free end of terminal half-wave doublet and close quarter-wave symmetrical dipole asymmetricly.

Description

The present invention relates to be used to receive and send the antenna of electromagnetic energy.
People know a kind of antenna that comprises axial arrangement at two half-wave doublets on one side at least.The half-wave dipole of per two disposed adjacent is all respectively held with the inductance phase-shift circuit of phase shift 180 degree and is joined, and the spacing between the oscillator is λ/δ.The most a half-wave doublet dead end is not that active antenna connects end.
The shortcoming of this known antenna is that its efficient is lower, and promptly its gain is big inadequately.
The objective of the invention is for a kind of antenna that improves gain is provided.
For achieving the above object, antenna of the present invention comprises that " n " is opposite to same axial half-wave doublet, couples together with the corresponding phase-shift circuit with inductance characteristic between every pair of half-wave doublet.The active end of antenna then draws a free end in the half-wave doublet of the most not holding.According to the present invention, one side the half-wave doublet of same two ends on axially always dispose a quarter-wave symmetrical dipole, the dead terminal of antenna then draws from the quarter-wave oscillator adjacent to active end.Being connected between each is to half-wave doublet and between terminal half-wave doublet and separately the quarter-wave symmetrical dipole is capacitive character, and perception and capacitive phase shift 60 to 120 simultaneously spent.
The angle that we recommend above-mentioned perception and capacitive phase shift is 90 degree.
The advantage of antenna of the present invention is that antenna efficiency is improved, and promptly it has higher gain, and has increased the efficient of antenna.
Each accompanying drawing shows an embodiment of antenna of the present invention, wherein:
Fig. 1 has represented to have " n " basic realization to the antenna of half-wave doublet;
Fig. 2 has represented to have the realization of the antenna of a pair of half-wave doublet;
The antenna of Fig. 1 comprises that " n " that be configured on axes O-O is to half-wave doublet 1 1, 1 2, 1 n, promptly half-wave doublet is to 2 1-3 1; 2 2-3 2; 2 n-3 nAbove-mentioned half-wave doublet is to 2 1-3 1; 2 2-3 2; 2 n-3 nEach abutting end respectively with inductive phase-shift circuit 4 1, 4 2... 4 nLink to each other phase-shift circuit phase shift 60 to 120 degree.Each is to half-wave doublet 1 1, 1 2..., 1 nBetween be that capacitive character connects 5, its phase shift 60 to 120 degree.Half-wave doublet 2 on two ends of same axial 0-0 1, 3 nOne side always dispose a quarter-wave symmetrical dipole 6,7.6,7 with half-wave doublet 2 1, 3 nBetween have one to connect 8.Connect 8 and have the capacitive behavior of phase shift 60 to 120 degree.First half-wave doublet 2 1Free end be the active end of antenna, it links to each other with the inner wire of coaxial line 9, the abutting end of quarter-wave symmetrical dipole 6 then is the dead terminal of antenna, it links to each other with the outer conductor of the ground connection of coaxial line 9.The terminals of antenna can be drawn and be introduced by the free end of the abutting end of last half-wave doublet 3n and its quarter-wave oscillator 7.
According to the antenna of Fig. 2, it comprises a pair of half-wave doublet 2-3, has connected the inductive phase-shift circuit 4 of energy phase shift 60 to 120 degree between half-wave doublet, and this phase-shift circuit is realized by a coil.The two ends of a pair of half-wave doublet 1 on same axial 0-0 always dispose one by connection 8 and the quarter-wave symmetrical dipole 6,7 of half-wave doublet to linking to each other, and connecting 8 can capacitive character phase shift 60 to 120 degree.Above-mentioned connection 8 is to be realized by the air gap between quarter-wave symmetrical dipole 6,7 half-wave doublet 2,3 adjacent with it.The active end of antenna draws the free end from half-wave doublet 2, and its dead terminal then draws the abutting end from quarter-wave symmetrical dipole 6.Active end also can be taken from the free end of half-wave doublet 3, and dead terminal also can be taken from the abutting end of quarter-wave oscillator 7.
To the change of above-mentioned antenna, can realize multiunit antenna system.Be equipped with suitable amplitude one phase place feed between each oscillator of these antenna system, and suitable in addition adjustment.
Above-mentioned antenna can be used for receiving and the transmission electromagnetic energy.It by row's conllinear and the hocket half-wave doublets of capacitive character and inductive phase shift of from 60 to 120 degree form.6,7 functions that play collaborative oscillator of quarter-wave oscillator wherein.
Antenna as shown in Figure 2, it is by forming in the half-wave scope of a pair of 160MHz to 200MHz of being operated in and through the half-wave doublet of inductive and capacitive phase shift 90 degree.This antenna can obtain the gain of 5.7db with respect to half-wave dipole on the 168MHz frequency.When this was operated in the branch half-wave scope of 450MHz to 540MHz to half-wave doublet, the gain with respect to half-wave dipole on the frequency of 525MHz was 4.4dB.
Table 1 has been listed by the gain of the expection of the various antennas of the present invention's realization and the gain of prototype antenna, so that their are done one relatively.
Figure 88100814_IMG2
His-and-hers watches 1 are analyzed and can be seen: antenna of the present invention is similar in its gain under the situation of prototype antenna, and its corresponding effective aperture electrical length is than the little twice of prototype antenna.
Above-mentioned antenna adopts asymmetric terminals, thus can be directly and non-symmetric line join, for example, can be directly and coaxial line join.The connection of non-symmetric line also available one connects the oscillator unit and realizes.Connect the unit with a symmetrical oscillator and one and also can realize being connected between antenna and the line of symmetry.
